- Add a `message-publisher` slot to `jupyter-request`, set when
sending a request.
- `*-request` functions now return a delayed request value instead of
a request. Update call sites.
- Add the functions `jupyter-messages`, `jupyter-idle`,
`jupyter-message-subscribed` and `jupyter-client-subscribed`.
- Move client subscription to a request's messages to
`jupyter-client-subscribed`.
- Request callbacks are now added via `jupyter-message-subscribed`.
- Reduce usage of callbacks in favor of searching `jupyter-messages`
where appropriate.
- Update tests
`jupyter-websocket-io` now returns, in addition to an IO function, a
kernel action subscriber. A client now sends messages to the
subscriber to interrupt or shutdown a kernel instead of doing so using
a `kernel` slot.
Also add the `jupyter-kernel-action` convenience function for
evaluating arbitrary code on a client's kernel.
This was mainly used when having to refresh the websocket connections
to a server after a REST request. Refreshing the websocket
connections is now handled internally to the connection of a
`jupyter-server`.
* jupyter-server-kernel.el
(initialize-instance): Add `kernel-ids` variable, modify it when
connecting/disconnecting kernel channels to the server's websocket
connections. When starting the subprocess that handles websocket
connections, re-connect any previously connected kernels.
(jupyter-server--refresh-comm): Remove.
(jupyter-server-kernel-connected-p): Remove.
(jupyter-api-request): Use `jupyter-start`/`jupyter-stop` when
refreshing websocket connections.
(jupyter-server--connect-channels): Use `jupyter-ioloop-wait-until`.
(jupyter-connection): Remove `jupyter-server-kernel-connected-p`
call.
* jupyter-kernel-process.el
* jupyter-server-kernel.el (jupyter-kernel): New method.
* jupyter-kernel.el (jupyter-kernel): Convert. Load files that handle
keywords and re-dispatch when ARGS does not have any connection
info. Document behavior.
* test/test-helper.el (jupyter-test-with-kernel-client)
* jupyter-server.el
(jupyter-connect-server-repl)
(jupyter-server-start-new-kernel): Use `jupyter-kernel`.
